IIO fixes for v3.6-rc1 

These mostly consist of fixes from Lars-Peter Clausen that were
 the first part of a large series reworking the drivers concerned.
 Turns out these drivers had quite a wealth of minor bugs.
 
 Also here are some build warning fixes for lm3533-als and
 adjd_s111 (both new drives in this cycle).
 Final elements are a a div factor overflow and a warning
 related fix in a couple of Analog Devices drivers.
 
 All in all nothing major, but a worthwhile bunch of short
 fixes.
